Understanding the Computer Analysis

Hi there,

I use the computer analysis for all of my games, but really only get benefit from the moves it identifies as blunders and mistakes. What do the numbers mean on moves that are not rates as blunders/mistakes, and what is the final number that climbs as the game progresses?

I presume it is how far from perfect you played, but how do you read it, and how do find out what the best move was in those situations where you have played a substandard move that is not classifed as poor enough to warrant the computer offering an alternative line?

Any help appreciated.

These 2 arcticles should help you understand a litle bit how computers evaluate chess positions. 

Wow, this forum is active, I completely lost this thread. Thanks for the replies - I'm using the computer analysis available if you are a premium member, but I'm sure the replies and links are relevant to all programs.

Cheers.
